Which process mainly helps in forming a rock pedestal?
Answer and explanation
Correct answer: Greater wind abrasion near the ground by sand grains
A rock pedestal, or mushroom rock, forms when wind-driven sand abrades the lower part of an exposed rock more intensely than its upper part. Sand grains are concentrated near the ground, so undercutting produces a narrow base and a wider top. Option A is correct. Coral growth, deltaic deposition, and cave calcite deposition are unrelated processes and do not create this aeolian shape.
